Logged into my rogue in Neverwinter and did an invocation. Apparently I was close enough to max level for that to push him over the top.
His gear was so-so before he hit level cap. Not enough to do decent DPS, but at least he’d survive most solo quests. As is the case in most MMOs, hitting level cap opens up a whole category of gear you had no access to before. As a result, what he has is REALLY bad now.
I’m not too concerned, though. I learned early on that I’m not particularly good at playing a rogue, so he mostly hangs out in town doing Alchemy and Leadership profession tasks.
